如果你有兴趣在一个语句中写一个If +AND/OR，那么它没有任何一个。但是，你仍然可以将if与&&/||和(/)语句组合在一起，以实现你想在一行中w/o任何额外变量和w/o if-else块复制(TRUE和FALSE代码段的单个echo命令):

@echo off
    
setlocal
    
set "A=1" & set "B=2" & call :IF_AND
set "A=1" & set "B=3" & call :IF_AND
set "A=2" & set "B=2" & call :IF_AND
set "A=2" & set "B=3" & call :IF_AND
    
echo.
    
set "A=1" & set "B=2" & call :IF_OR
set "A=1" & set "B=3" & call :IF_OR
set "A=2" & set "B=2" & call :IF_OR
set "A=2" & set "B=3" & call :IF_OR
    
exit /b 0
    
:IF_OR
( ( if %A% EQU 1 ( type nul>nul ) else type 2>nul ) || ( if %B% EQU 2 ( type nul>nul ) else type 2>nul ) || ( echo.FALSE-& type 2>nul ) ) && echo TRUE+
    
exit /b 0
    
:IF_AND
( ( if %A% EQU 1 ( type nul>nul ) else type 2>nul ) && ( if %B% EQU 2 ( type nul>nul ) else type 2>nul ) && echo.TRUE+ ) || echo.FALSE-

    
exit /b 0

更统一的版本:

@echo off

setlocal

set "A=1" & set "B=2" & ( call :IF_AND "%%A%% EQU 1" "%%B%% EQU 2" && echo TRUE+ ) || echo FALSE-
set "A=1" & set "B=3" & ( call :IF_AND "%%A%% EQU 1" "%%B%% EQU 2" && echo TRUE+ ) || echo FALSE-
set "A=2" & set "B=2" & ( call :IF_AND "%%A%% EQU 1" "%%B%% EQU 2" && echo TRUE+ ) || echo FALSE-
set "A=2" & set "B=3" & ( call :IF_AND "%%A%% EQU 1" "%%B%% EQU 2" && echo TRUE+ ) || echo FALSE-

echo.

set "A=1" & set "B=2" & ( call :IF_OR "%%A%% EQU 1" "%%B%% EQU 2" && echo TRUE+ ) || echo FALSE-
set "A=1" & set "B=3" & ( call :IF_OR "%%A%% EQU 1" "%%B%% EQU 2" && echo TRUE+ ) || echo FALSE-
set "A=2" & set "B=2" & ( call :IF_OR "%%A%% EQU 1" "%%B%% EQU 2" && echo TRUE+ ) || echo FALSE-
set "A=2" & set "B=3" & ( call :IF_OR "%%A%% EQU 1" "%%B%% EQU 2" && echo TRUE+ ) || echo FALSE-

exit /b 0

:IF_OR
if %~1 ( exit /b 0 ) else if %~2 ( exit /b 0 ) else exit /b 1
exit /b -1

:IF_AND
if %~1 ( if %~2 ( exit /b 0 ) else exit /b 1 ) else exit /b 1
exit /b -1

输出:

TRUE+
FALSE-
FALSE-
FALSE-
    
TRUE+
TRUE+
TRUE+
FALSE-

诀窍在于type命令，它删除/设置errorlevel，从而处理到下一个命令的方式。

另一种选择是寻找unix shell，它可以提供逻辑操作符和更多的功能。如果您不想走cygwin路线，您可以在这里获得Bourne shell的本地win32实现。本地bash可以在这里找到。我很确定你可以很容易谷歌其他好的替代品，如zsh或tcsh。

你可以用嵌套条件做和:

if %age% geq 2 (
    if %age% leq 12 (
        set class=child
    )
)

or:

if %age% geq 2 if %age% leq 12 set class=child

你可以用一个单独的变量:

set res=F
if %hour% leq 6 set res=T
if %hour% geq 22 set res=T
if "%res%"=="T" (
    set state=asleep
)

注意，这个答案是针对cmd批处理语言定制的，在Windows中可以找到。你提到了“DOS批处理”，但是，基于几点，我认为前者的选择是一个安全的赌注(1)。

如果你真的是指原始的MS-DOS批处理语言，你应该记住If语句要简单得多，你可能需要使用If语句的块…Goto表示控制流，而不是(例如)括号或其他。

(1)以下几点支持:

The presence of the cmd and windows-console tags; Prior experience of some people failing to recognise the very real difference between cmd and MS-DOS batch languages, and conflating DOC with the cmd terminal window; The question using the more generic "DOS" rather than specifically "MS-DOS" (where "DOS" could possibly be any disk operating system; The fact this is Stack Overflow rather than the retro-computing sister site, where a question about MS-DOS would be way more appropriate (I'm often on that site as well, it's nice for those of us who remember and appreciate computer history); and The (eventual) acceptance of the answer by the original asker, indicating that the solution worked.

OR有点棘手，但也不过分。这里有一个例子

set var1=%~1
set var2=%~2
::
set or_=
if "%var1%"=="Stack" set or_=true
if "%var2%"=="Overflow" set or_=true
if defined or_ echo Stack OR Overflow

这就像下面这样简单:

如果和>如果+

if "%VAR1%"=="VALUE" if "%VAR2%"=="VALUE" *do something*

OR> if // if

set BOTH=0
if "%VAR1%"=="VALUE" if "%VAR2%"=="VALUE" set BOTH=1
if "%BOTH%"=="0" if "%VAR1%"=="VALUE" *do something*
if "%BOTH%"=="0" if "%VAR2%"=="VALUE" *do something*

我知道还有其他的答案，但我认为我的答案更简单，所以更容易理解。希望这对你有所帮助!；）

德摩根定律允许我们只使用连词(“与”)和否定(“非”)将析取(“或”)转换为逻辑等价。这意味着我们可以将析取(“OR”)链到一行上。

这意味着如果名字是“Yakko”或“Wakko”或“Dot”，那么就呼应“Warner兄弟或姐妹”。

set warner=true
if not "%name%"=="Yakko" if not "%name%"=="Wakko" if not "%name%"=="Dot" set warner=false
if "%warner%"=="true" echo Warner brother or sister

这是paxdiablo的“OR”示例的另一个版本，但条件被链接到一行上。(注意leq的反义词是gtr, geq的反义词是lss。)

set res=true
if %hour% gtr 6 if %hour% lss 22 set res=false
if "%res%"=="true" set state=asleep
